[WIP] - Creature Sculpt

Hi Guys, this is my first polycount post so Im a little nervous, heres a character sculpt based of a very talented friend of mine's concept art of Bezzy. (Attached below.) I started replicating but as the sculpt went on to a more realistic character i tweaked a few things and made it a little less friendly. Its a long way off finished and i was hoping to get so constructive crit, especially Im still confused as to what to do with the extruding wing like parts of the character, whether to make it wafer thin skin or chucky and muscular based.

So please if theres anything you would like to suggest or have any input please let me know.
